Description
Technical Field
The invention relates to the technical field of high-carbon alcohol production, in particular to high-carbon alcohol separation and purification equipment.
Background
The high-carbon alcohol refers to monohydric alcohol with carbon number more than or equal to 8, is commonly used for synthesizing fine chemical products such as surfactants, plasticizers, detergents and the like, and is widely applied to the fields of petrochemical industry, mechanical mining, architectural metallurgy, papermaking, food and the like. Currently, the main synthesis methods of higher alcohols are oxo, ziegler and normal alkane oxidation, and the preparation raw materials mainly originate from petroleum derivatives. The refinery or coal chemical industry enterprise utilizes low carbon olefin resource, produces aldehydes with increased carbon atoms through hydroformylation reaction, further produces high carbon aldehydes, and then obtains high carbon alcohol products such as 2-PH and the like through high carbon aldehyde hydrogenation reaction. In the production of higher alcohols, there is often a large amount of waste alcohol liquor generated, and the problem of treating waste alcohol liquor of 2-PH is relatively serious compared with butanol and octanol. The method is characterized in that the waste alcohol liquid generated in the preparation process of the high-carbon alcohol still contains a large amount of high-carbon alcohol products and active intermediate components thereof, wherein the active intermediate components comprise enol and aldehydes which can be converted into the high-carbon alcohol, and the waste alcohol is large in emission and difficult to directly utilize. At present, waste alcohol is mainly treated in a combustion mode in industry, so that serious resource waste is caused.
The Chinese patent with the application number of CN109503322A discloses a process method for preparing high-carbon alcohol from paraffin, and relates to a process method for preparing high-carbon alcohol, which comprises the following process steps: adding solid paraffin and boric acid into a three-mouth bottle, heating and stirring, and stopping heating and stirring after the constant-temperature reaction to obtain an intermediate product; cooling, adding sodium hydroxide solution into the flask, and heating for hydrolysis to obtain a crude high-carbon alcohol mixture; transferring the reaction product into a 250ml separating funnel, adding 70 ℃ deionized water, stirring, standing to separate a water layer, retaining an upper oily substance, and repeating the operation until the pH value of the water layer is neutral; transferring the obtained crude product into a three-mouth bottle, adding 20ml of toluene solution, distilling under reduced pressure until the water quantity has no obvious change, and then drying the product at the constant temperature of 50 ℃ until the weight is constant. However, the preparation conditions of the method are strict, the cost of the preparation raw materials is high, and the method is difficult to popularize in industry.
The Chinese patent with the application number of CN102850181A discloses a preparation method of high-carbon alcohol, which comprises the following steps: in a tubular reactor, introducing a mixture of hydrogen, fatty acid methyl ester and C1-C4 alcohol into a fixed bed reactor filled with a hydrogenation catalyst, carrying out hydrogenation reaction at the temperature of 200-320 ℃ and the pressure of 3.0-7.5 MPa, distilling reaction effluent to separate target product higher alcohol, wherein the hydrogenation catalyst has the following general formula: zncuaacrbmcox. However, the waste liquid obtained after the high-carbon alcohol is separated by the method still contains more products, and the products cannot be recycled.
